Actors Manoj Pahwa and Rajat Kapoor swapped roles for Anubhav Sinha's courtroom drama Mulk, starring Rishi Kapoor and Taapsee Pannu. While Rajat was to initially essay Rishi's younger brother in the film, Manoj was to play a tough cop.

Sinha said in a statement: "I always wanted Manoj Pahwa and Rajat Kapoor in the primary cast for Mulk. While I had envisaged a different role for both of them in the film, it was only when they came in together on sets after the recce did I realise that they were both meant to play different roles. They were both pretty quick in adapting to a new role.''

The teaser of the film shows Rishi Kapoor playing a character called Murad Ali Mohammed, accused of treason. Actress Taapsee Pannu plays his defence lawyer Aarti Mohammed.

Rishi is happy about working with Rajat. "Though we have worked in just two films, a lovely co-actor and poker player, Rajat Kapoor. The only irritant about him is he is a teetotaller, unlike me, and doesn't carry a mobile. An under-used actor waiting to burst. Go man go," Rishi tweeted.
